Hi if anybody van help me a week ago my uno overheated no water in the oil coolant was gone from the radiator thank i replaced the water pump as it was broken that solved the coolant leaking problem but now my radiator fan wont work any help please

Does car overheat? Or is it not hot enough to make fan work?

Check fan works. If the fan switch was two wires, join the wires with a piece of wire, the fan should come on! If it does and the car overheats, it needs a new sensor in the radiator.....

If the fan does not work when you put wire across the switch, check for live and earth at fan,while wire across switch....

Live and earth ok then new fan needed. If no live and earth ...electrical problem....

i connected the fan to the battery it works fine the car does overheat yes and still no fan i will check sensor on the radiator thank u
